DOOR-OPERATING- MECHANISM.

Application filed April 3,

To all whom it may concern:

Be it known that l, HARRY S. HART, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Door-OperatingMechanism, of which the following is a specification.

The present invention relates to sockets.

More particularly the present invention relates to the construction ofrailway cars of the dumping type wherein it is required to turn a shaftto operate dump doors.

An object of the present invention is to provide shaft operating meansfor dump doors which may be readily engaged by a wooden or other bar foroperating a shaft.

A further object is to provide a shaft operating member which may belocated in an inconspicuous and unobtrusive position but which may beconveniently operated.

A further object is to provide a shaft operating member for dump doors,said member having means for biting into a wooden or similar bar wherebyslippage will be prevented.

Further objects will appear as the description proceeds.

Referring to the drawings Figure 1 is a cross sectional view of a rail`way car of the dumping type illustrating the applicability of thepresent invention;

Figure 2 is a View, on an enlarged scale, of the embodiment shown inFigure 1;

Figure 3 is a view taken in the direction of the arrows 3 3 of Figure 2;

Figure a is a view taken in the direction of the arrows 4-4 of Figure 2.

The numeral 1 indicates a railway car having the sides 2 2. The numerals3 3 indicate dump doors located at the bottom of the car cooperatingwith the floor portions 3 3 of said car, which doors are adapted toswing downwardly to dump the load. Said doors 3 3 are operated bymechanism connected with the longitudinally extending shaft 4, whichmechanism is not illustrated herein inasmuch as it forms no part of thepresent invention. The longitudinally extending shaft 4: may be drivenby the gear 5, which in turn is operated by the worm 6. Said worm isfast on the transversely extending shaft 7 and has motion communicatedthereto by reason of rotation of said shaft 7. Said shaft 7 may be 1922.Serial No. 548,950.

supported by brackets 8 8 which form bearings and which are locatedadjacent to the sides of the car whereby turning effort applied to saidshaft 7 at either end of said shaft will have a minimum distortingeffeet upon said shaft.

According to the present invention, each end of the shaft 7 is providedwith a socket 9. The sockets 9 9 may be castings of steel or othermaterial and may be cored out to provide a portion 10 for receiving anend of the shaft 7, said portion being secured to the shaft 7 by meansof the pin 11. Each of the sockets 9 may be provided with a cylindricalouter portion 12 adapted to contact with a bearing 8 referred to above,by rea-son of which construction, finishing operations on the shaft 7are minimized. The socket 9 is cored out to provide a lever receivingportion 13. The interior of said portion 13 may have a cross sectionalcontour wedge-shaped at both ends, as indicated in Figure 3, though awide field of choice is possible in said cross sectional contour. Theconstruction illustrated has certain advantages, however, inasmuch as itreadily adapts itself for gripping a lever of wood or similar material.Teeth 1% 14 are provided at both ends of the lever receiving portion 13,said teeth being located at thewedge-shapedportions thereof.

The lever receiving portion 13 of the socket 9 will preferably have itsaXis arranged at an angle other than a right angle with reference to theaXis ofthe shaft 7, the preferred construction being clearly indicatedin Figures 1 and 2. By reason of the angular relation between the leverreceiving portion 13 of the socket 9 and the shaft 7, the socket 9 maybe located within the overall dimensions of the car, and a lever such asindicated by the numeral 15 will clear the side of said car whereby saidlever may conveniently be operated.

By reason of the gripping ends of the portion 13 and by reason of theteeth 14 14 in said portion 13, a lever 15 of wood or similar materialwill be tightly gripped when pressure is applied thereto, whereby therewill be no tendency to slip. This gripping eect, however, will notinterfere with the ready removal of the lever, the net advantage beinggained that workmen may conveniently dump the doors on a number of cars,one after another, expeditiously and with a minimum ot danger ot havingthe levers slip relative to the operating ineinlier.

One embodiment ot the present invention has been described in detail.Many ineditications Will occur to those skilled in the art. It isintended in this patentA to cover all such modifications that tallWithin the scope oit the invention as detined by the appended claims.
